For decades, humans and global climate change have been threatening the existence of polar bears. Scientists in Alaska are working hard to save as many of them as possible. VOA’s George Putic reports.
The zoo in Anchorage, Alaska, has been taking care of orphaned or abandoned polar bears since the 1970s
Texas college professor teaches students how people can live with much less than what average American consumes
A Texas college professor wanted to teach his students how people could live with much less than what the average American consumes, so he decided to set up living conditions for a year - on a rotating basis - for one person in a space of about three square meters. It's in a metal dumpster that is typically meant for trash. His experiment is attracting a lot of attention. VOA’s George Putic has more.
Angered over U.S. sanctions against Russian officials involved in the annexation of Crimea, and unrest in Eastern Ukraine, Russian deputy Prime Minister Dmitry Rogozin said Moscow may retaliate by re-assessing the space cooperation between the two countries. VOA’s George Putic reports.
Angered by US sanctions over Ukraine dispute, Moscow might retaliate by reassessing space-related collaborations between both countries
Irish scientist finds way to mass produce graphene, which is stronger than steel and best conductor of heat and electricity
A relatively new substance called graphene is being hailed as the wonder material of the 21st century but no one has developed a way to mass produce it. However, one Irish scientist says he may have a solution. VOA's George Putic reports.
New fuel was tested successfully on a model airplane with a two-stroke engine; for now, making it requires twice as much power as fuel can produce, though researchers hope to lower that ratio
For centuries, alchemists have tried to turn lead into gold. That transmutation has long been proven impossible, but another similar dream - turning water into fuel - seems to be achievable. Scientists at a U.S. Naval Laboratory proved it by flying a model airplane burning re-engineered seawater. VOA’s George Putic has the story.
International research team in Switzerland builds robotic arm that performs complex movements
An international team of engineers based in Switzerland built a robotic arm that learned to perform complex movements. VOA’s George Putic reports.
The threat to close stations that monitor signals form US Global Positioning Systems follows Moscow's announcement that it will ban the US from using Russian rocket engines for space launches
Space rocks often enter the Earth’s atmosphere and usually explode and burn before falling to the ground. About 70 percent of our planet is covered with water so most of them disappear on the oceans’ floor and we would not know about them if it was not for an international agency. VOA’s George Putic reports.
From 2000 to 2013, at least 4 were stronger than nuclear bomb that destroyed Hiroshima
Such transistors could someday be used for building flexible high-resolution displays that need very little energy
Evidence of next element on list, element 118, has also been found
Most of the naturally-occurring elements have already been discovered, but that does not mean that new elements cannot be created - only that they are too unstable to exist for a long time. Australian scientists recently reported creation of a new, super-heavy element. VOA’s George Putic has more.
Service dogs almost never leave their owners, even on public transportation, but a busy airport environment can be disorienting and distressing
